Application filed August 2, 1922. Serial No. 579,256.

To all whom it may concern:

Be it known that we, EMILE SoHEE- MACKER and GEORGES RAIMOND, citizens of the United States, residing at VVoonsocket,

county of Providence, and Bellingham, in the county of Norfolk, respectively, and

States of Rhode Island and Massachusetts,

respectively, have invented certain new and useful Improvements in Aeroplanes, of which the following is a specification.

The present invention relates to means for assistin aviators to clear themselves from aeroplanes in case of accident and reach the ground in safety.

The object is to provide a simple apparatus of a practical character and one that is under the control of the aviator for ejecting him from the fuselage and permit him to jump without danger of entanglement.

The preferred embodiment of the invention is shown in the accompanying drawings, wherein I Figure 1 is a view in side elevation with the parts in normal or inoperative condi- 25 tion,

Figure 2 is a similar view, but showing the apparatus in its ejecting relation,

Figure 3 is a detail sectional view with the parts as shown in Figure 1,

Figure 4 is a detail sectional view with the e ecting means extended,

Figure 5 is a front elevation of the mechanism shown in Figure 4.

The aeroplane, which may be of any desired character, is shown as provided with a standard type of fuselage 6 and planes 7, the upper plane having a central recess 8 in its rear side, as indicated in Fi re 2.

An upwardly movable seat 9 is located in the. fuselage and is pivotally mounted, as shown at 10, to the upper end of lazy tongs 11, said tongs being mounted by a pivot pin 12' at its lower end in the lower portion of the fuselage. Suitable cross springs 13, connecting opposite sections of the lazy tongs, serve to urge the same towards each other and thus extend the tongs in a well known manner. Ordinarily, however, these tongs are maintained in collapsed or folded condition, beneath the seat, as shown in Figure 3.

This holding means includes a, pair of oppositely disposed latch levers 14 carried by the seat, and having pins 15 that enga e in sockets 16 in the opposite side walls 0 the fuselage. The levers terminate at their upper ends in suitabl hand grips 17. Other holding means comprise oppositely disposed hooks 18 pivotally mounted in the lower portion of the fuselage, as shown at 19, said hooks being arranged to take over cross pins 20 on the lower end of the lazy tongs. The hooks 18 are connected by an equalizer bar 21, and this bar has a pivotal connection 22 with an actuating lever 23. The lever 23 is connected to a foot treadle 24 arranged in advance of the operators seat 9.

Said seat 9 has connected to its rear lower portion a coiled spring 25 which is also connected, as shown at 26, to the lazy tongs. This spring serves to turn the seat 9 rearwardly upon the lazy tongs when the latter are extended. A foot piece 27 is pivotally mounted on the lower front side of the seat so that it maybe folded up against the same, and chains or other fasteners 28 serve to limit its downward movement to a horizontal position.

The fuselage is provided directly in rear of the seat-retalning recess with a para-' chute pocket 29 having an upwardly moving bottom 30 carried by springs 31. A cover 32 for the pocket has a spring hinge 33 which serves to swing said cover upwardly. The cover, however, is normally held in closed position-by a rearwardly extending flange 34 that overlies the same and is carried by the seat 9.

The operation of this apparatus is substantially as follows. Under normal conditions the seat 9 is held down in the fuselage by the hooks l8 and the latches 1415. In case of an accident the aviator has only to release the latches 14 15 and press upon the treadle 24. The seat being thus released, the springs 13 will cause the elongation of the lazy ton s and eject the seat from the fuselage. Kt the same time the spring 25 will act to swing said seat so that as the aeroplane plunges downward the seat will be in approximately horizontal position and the aviator standing upon the foot piece 27 as indicated in Figure 2, will be free from contact with the lane.

A parachute, as A, to which the aviator 1s strapped, is carried in the pocket 29 upon the plunger bottom 30 and 1s normally held therein by the cover 32 which in turn is held in closed position by the-flange 34 of the seat. As said seat rises, obviously the cover 33 will be released .and the plunger Having thus fully dwcribed our inven-' tion, what weclaim as new, and desire to secure by Letters Patent, is:

1. In an aeroplane, a fuselage, a seat member movably mounted therein, a lazy tongs on which the seat is moun, mes for elongating the lazy tongs to eject the seat from the fuselage, and means for normally lockingithe seat against such ejection.

2. In an aeroplane, a lage, a seat member movably mounted therein, a lazy tongs on which the seat is mountw, springs ened with the lazy tongs for e ecting the seat from the fuselage, and -.--.=11-= (ill ' between the seat and ejecti permits the former to tilt with respect to for normally locking the smt againm such ejection. x=

3. In an aeroplane, a fuselage, a seat memher movably mounted therein, a lazy tongs on which the seat is mounted, means for elongating the lazy tongs to eject the seat from the fuselage, holding hooks engaging the lazy tongs to hold them in collapsed condition and means for operating the hooks to release the lazy tongs.

4. In an aeroplane, a fuselage, a seat member movably mounted therein, a lazy tongs on which the seat is moun, ms for elongating the lazy tongs to eject the seat from the fuselage, oppositely di MIR-Pl] pivoted. holding hooks r 1 the lazy tongs. to hold them in gum-.1 condition,

an equalizer bar conning the tongs, and

an actuating device connected to the equaliziiug bar.

5. In an. aeroplane, the combination with a fuseli; of a seat removable therefrom, means for ejecting the seat, a connection n: that the ejecting means, and means for automatically causing the seat to tilt when ejected.

6. In an aeroplane, the combination with a fuselage, of a seat removable. therefrom,

m for ejecting the seat, a pivotal connection between the t and the e ecting naraaaa ing movement.

In an aeroplane, the combination with a fusel of a seat removable therefrom, means for ejecting the seat, a pivotal connection between the seat and the ejecting me that permits the former to tilt on the latter, and a spring between the seat and eject mgr a: no for swing said seat.

8. In an aeroplane, the combination with a fuselage, of a lazy tongs mounted therein, means tor ding the lazy tongs, means for looking the lazy tongs against extension, a.- seat pivoted on the lazy tongs, and .-a-. a for swng the seat when the lazy tongs are extended.

9. In an aeroplane, the combination with a fuselage, of a lazy tongs mounted therein, sp

us for a; the lazy tongs against extension, a seat pivoted on the lazy tongs, and aspiring for swinging the seat when the laz tongs exmnded.

10. ii an aeroplane, the combination with a fuselage, of a seat, means for ejecting the seat from the age, a arachute pocket in the fuselage in rear of t e seat, a cover for the pocket, and means carried by the seat for holding the cover closed.

11. In aeroplane, the combination with a of a seat; means for ejecting the swt from the fumlage, a parachute pocket in the fuselage in rear of the seat, a spring opted cover for the pocket, means carried by the seat and removable therewith for holding the cover cl, and

a spring-pr ejector for the parachute located in the pocket.

12. In an aeroplane, the combination with natures in'the a ence of two witnemes.
